WIRE-GALVANIZING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 301,571, dated July 8, 1884. Application filed December 21, ldES. (No model.)

' a perspective view of the bed I.

This invention relates to certain improvements in awire-galvanizing apparatus, and pertains to the wiper-box for cleaning and brightening the wire, and certain improvements in the furnace, which improvements I will fully explain in the following specification.

Referring to the drawings, B represents the bath to hold the molten galvanizing material surrounded by the briclrfurnace for holding the fuel around the bath. The wire to to be galvanized passes through the bath B, as shown in Fig. 1,and travels in the direction of the ar row, first passing under the deep sinker a, from thence under the pivoted sinker z, of which there is a separate one for each wire. It then passes into the wipe-box cl, into the funnelshaped openings 112; m which are filled with some suitable noncombustible material-such as asbestos, or any suitable material for wiping the superfluous galvanizing metal off the wire. These funnel-shaped openings are formed in the face of the bed P, as shown in Fig. 3, and in the lower side of the head c-one-half in each, so that when the two close together, as shown in Fig. 2, they form a funnel-shaped hole or opening, having the large end toward the bath B. The small end prevents the filling m from being carried through by the wire. The

asbestos filling is placed in between the bed P- and head a, so as not only to fill the funnelshaped openings or holes m m but also between the adjacent parts, as shown in Fig. 2. The bed 1? and head 0 are placed in the rect- I angular box or compartment d, asshown in Fig. 1, so they maybe removedby raisin g them out vertically with a crane. The sides of the compartment cl are provided with inlet'holes o for the wire to to enter, and exit-holes o for the wire to pass out into the sand S. It is in tended to weight the head 0, so as to applv great pressure on the asbestos or filling between it and the bed I, so as to compress it very compactly, so as to give considerable friction to the wire as it is drawn through. Ad-

- ditional w eights, c 0 c", are added to give greater. pressure to the wiping-filling.

The headc is provided with a pair of rods, 15 t, which are screw-threaded on their lower end, and screw in said head, and are united at the upper end by abail, a, hooked into the link-nuts t t, which may be removed to place on the-weights c" 0 c, which are perforated to slide down over said rods 13 t. The bail a is used so that a crane may attach thereto and raise all the weights and head 0 out, when desired. The box or compartment d is provided with a door, a, hinged at h h thereto in front of the funnel-shaped holes 12?. W, for the purpose of gaining access to clean them out, should they become clogged with superfluous galvanizing metal. The sand S, into which the wire emerges from the wipe-box or wiping material in the box (Z, is for the purpose of brightening and polishing 7 5 the wire. The sand-box has an inclined bottom hinged at its lower end and adapted to be let down at its upper end, as shown by the dotted lines in Fig. 1, to empty and clean out the sand-box a. A rod, 0?, holds the sand-box a together, and, when loosened, will permit the bottom a tofall, as shown. The sinker A is pivoted at about its center on the cross-rod x, upon which it partially rotates, so as to elevate or-depress its lower end to hold the wire to down in the metal, or let it up. Its lower end is provided with a shoe, 2, in which the wire runs. The pin gpasses through said sinker under said rod m, to prevent the wire 20 from elevating said sinker, and y is a rest to 0 hold the sinker and cause it to stand vertically, as shown in Fig. 1. It is intended to have a train of these sinkers-one for each wire-a-nd that each wire shall pass through independently of the other. An eye in the up- 5 per end of this sinker A furnishes. means for attaching a crane to it to remove it from the bath,whendesired. Bythis process of applying a frictional wiper to the wire, all the superfluous galvanizing metal is thoroughly re- 10o moved, and also any lumps or inequalities smoothed down before the wire enters the sand, whose office is simply to brighten and polish the wire to avery high degree; also the'greater portion ,of the superfluous metal wiped off the wire by the wiping material in the funnels m m falls back into the bath and is saved, and not lost in the sand. In similar apparatus it has not been usual to line the vat V with any I am aware that a device for this purpose has been used,wherein the wire has been caused to pass through a funnel-shaped aperture out at its small end, for the purpose of scraping off the superfluous galvanizing metal from the wire, by means of its contact with the inner walls of the funnel,without the use of a compressed wiping-filling in the funnel, as in this invention Such construction I do not claim.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is as follows, to wit:

1. In the wire galvanizing apparatus described, the combination of the wipe-box d, head 0, and bed P, the head 0 and bed P having, respectively, the funnel-shaped opposite grooves, 112/ and m, forming the funnel-shaped aperture described, compressed wiping-filling m for the wire to to pass through, and means for compressing said filling on said wire, as and for the purpose set forth.

2. The combination of the wipe-box d,having the inlet-holes -v and exit-holes v, and door a bed P, having the funnel-shaped grooves m, head 0, having the funnel-shaped grooves m, compressed wiping-filling m, weights 0 c c, and means for operating the several parts, as and for the purpose set forth.

3. In the wire galvanizing apparatus described, the combination of the wipe-box d, having the inlet-holes o and exit-holes '0, compressed wiping-filling m for the wire to to be drawn through, and sand-box a for holding sand or any analogous material, all adapted to operate as and for the purpose set forth.
